IPC: B22D27/02
Filed: 1981-02-28
Abstract: PURPOSE:To break growing columnar crystals, to form the fine isometric structure from the surface of a alloy steel or high alloy steel ingot down to the axial center and to save a hot forging stage in casting of said ingot by electromagnetically agitating the unsolidified part from the period of starting casting of the molten steel into a mold of a nonmagnetic material. CONSTITUTION:Right after the start of casting by using a mold 1 of a nonmagnetic material, an electromagnetic agitating coil 2 provided on the outside surface of the mold 1 is moved upward in conformity with the ascending speed of the level of molten metal. Thence, the coil 2 is moved upward and downward along the mold 1 since the end of casting until the fine equiaxes crystal is grown on the surface of the steel ingot. Thereby, the need for hot forging of the steel ingot is eliminated in the case of making a pipe or the like from the ingot of alloy steel or high alloy steel vulnerable to formation of columnar crystal structure.

Title: Ignition timing controller for engine
Inventor: MACHIDA HISASHI
IPC: F02P5/155
Filed: 1987-02-09
Abstract: PURPOSE:To optimumize an advance angle regulation with quick responsiveness against the rising of engine speed by constant-current-discharging a condenser and also controlling an ignition timing as being compared with the output of a frequency-voltage converter. CONSTITUTION:A pick-up signal A synchronous with the revolution of an engine becomes a voltage signal B by means of a frequency-voltage converter 3, and by making its inversion signal a threshold value, the signal A becomes a pulse state corrugated-form arranging signal C by means of a comparator 6. On that occasion, the on-duty of a power-transistor Q can be voluntarily regulated by changing a time constant at the converter 3 by means of a time constant changeover circuit 4. And, the signal C is constant-current-discharged through a condenser by means of a constant-current-discharged circuit 7 and its discharge signal D is, by means of a comparator 8, discriminated with the signal B as a threshold value, and an angle advance is computed by it, and a base-drive signal E with the off-timing of the power-transistor Q controlled is obtained. Thus, a quick responsive angle advance regulation against revolution-rising is conducted most suitably, and the high revolutionization of the engine can be easily coped with.

Abstract: PURPOSE:To improve the adhesion between a non-magnetic substrate and thin gamma-Fe2O3 magnetic film and to prevent damage such as exfoliation of the magnetic film by providing an intermediate film laminated alternately with >=1 layers of the 1st Ti2O3 film and the 2nd Ti2O3 film by a specific method between the substrate and the magnetic film. CONSTITUTION:A TiO2 film 23 is deposited to 0.02mu thickness on an alumitetreated Al substrate 21 then a Ti film 24 is deposited to 0.1mu thickness on the film 23. A thin alpha-Fe2O3 magnetic film 25 is deposited to a prescribed thickness on the film 24 and thereafter the film is reduced and oxidized at about 300 deg.C by which a magnetic recording medium having the thin magnetic film 25a transformed to gamma-Fe2O3 is formed.

Title: Multiprocessor system
Inventor: MASUDA HIROKI
IPC: G06F9/30
Filed: 1982-02-24
Abstract: PURPOSE:To stop all processors simultaneously when the stop condition of one processor is satisfied, by adding only an additional circuit and a cable to the multiprocessor system having an address stop function in a simplex. CONSTITUTION:When the address of a program which a CPU executes coincides with a stop address, a comparator CMP generates a coincidence output. The coincidence output of the comparator CMP passes through a gate G2 and sets a flip flop (FF) at the timing of a clock T. The set output of this FF becomes an interrupt signal INT for the address stop to interrupt the CPU through a bus 50 for the address stop. A gate G4 of an operator 20 is turned on to lead the level of a multicable 9 into L, and gates G5 of other operators 21-2n are set to L simultaneously. When switches SW of operators 21-2n are all made, the FF is set through gates G5, G6 and G3 to generate the interrupt signal INT for the address stop to the CPU.

Title: Spread spectrum communication receiver
Inventor: GANJI NOBUO
IPC: H04B1/709
Filed: 1987-02-10
Abstract: PURPOSE:To correct the effect of signal distortion due to a signal transmission line and to demodulate data momentarily by a simple circuit by taking correlation between a signal retarding a reception signal by one period or a multiple of one period of a series of a pseudo noise signal and the reception signal itself and demodulating the result. CONSTITUTION:A correlation device 21 of a transmitter inverts the phase by 180 deg. and gives an output depending on '1', '0' of data 20 for a spread signal generated by a PN code (pseudo noise signal) generating means 19. One bit of the data has a time corresponding to one period of the PN code. A receiver 22 takes a correlation between a signal 25 retarding a reception signal 23 by one period of the PN code at a delay means 24 and the reception signal 23 by means of a correlation device 26. A delay means 24 consists of a delay line in case of an analog signal and a shift register in case of a digital signal. The output of the correlation device 26 is given to a low pass filter 27 and a data 28 is demodulated. Since the data 28 is information representing the level '1' or '0' to be inverted or the same before one preceding bit, the start bit is decided to be '0' or '1' in case of transmission and the actual data is sent from a 2nd bit.

Abstract: PURPOSE:To convert an inversion phenomenon into numerical data to record it by recording data obtained by A/D conversion of a video signal and processing this data. CONSTITUTION:The video signal is recorded and reproduced by a video signal recording and reproducing device 1 to be evaluated, and this video signal (a) is subjected to A/D conversion by a waveform memory 2 and is recorded as numerical data (b).

A number N1 of points to the rise part of the video signal from the horizontal synchronizing signal and a number Nh of points to the next horizontal synchronizing signal are obtained to continuously extract the video signal in the range of N1+ or -DELTAN from the start of one-line components of the video signal. The part in the range of N1+ or -DELTAN before recording and reproducing and that after recording and reproducing are compared with each other; and when the difference from white and black level parts of the video signal is equal to or higher than a certain level, the occurrence of an inversion phenomenon is decided. Thus, the inversion phenomenon is recorded as numerical data and is quantitatively evaluated in a reproduced picture.

CONSTITUTION:A control signal wiring 100 is divided into more than two parts and control signal input terminals 102 and 103 are provided in the both ends in the length-wise direction of the contact type image sensor. Then, a video signal output terminal 104 is provided in the almost central part in the length- wise direction thereof and the preamplifier (for example, a base ground amplifier circuit, etc.) of the low input impedance is connected to the video signal output terminal 104. The maximum value of delay to the control signal wiring is made effectively equal with the maximum value of delay to a video signal wiring. Thus, since the control signal wiring is divided into N parts, the maximum delay of the control signal wiring is made smaller by N<2> times. Accordingly, the reading operation at high speed can be realized.
